The lung can be thought of as a large number of interconnected bubbles that form the interface between the gaseous environment and the wet alveolar surface. If this interface were devoid of surfactant, two consequences would ensue: (1) every breath would take a considerable amount of pressure to expand the lung, comparable to the 80 to 90 cm H₂O of pressure required for a newborn's first breath and (2) the lung would rapidly collapse during exhalation.
